Developmental Trends: Language Skills at Different Age Levels (page 2)

Infancy (Birth–2)

What You Might Observe:

• Interest in listening to the human voice and in exchanging vocalizations with adults
• Repetition of vowel sounds (cooing) at age 1–2 months and consonant-vowel syllables (babbling) at about 6 months
• Understanding of some common words at about 8 months
• Use of single words at about 12 months
• Use of two-word combinations at about 18 months
• Rapid increase in vocabulary in the second year

Diversity:

• In the latter half of the first year, babbling increasingly reflects phonemes of the native language.
• Temperament may influence the development of expressive language; more cautious children may wait a bit before beginning to speak.
• Chronic ear infections can interfere with early language development.
• Infants with severe hearing impairments babble, but the quality of their babbling changes little over time. Spoken language progresses no further unless intensive training is provided.

Implications:

• Engage young infants in “conversations,” using simplified and animated speech (i.e., infant-directed speech) and responding when they vocalize.
• Label and describe the objects and events children encounter.
• Teach simple hand signs that preverbal infants can use to communicate.
• Ask simple questions (e.g., “Is your diaper wet?” “What does a cow say?”).
• Repeat and expand on children’s early “sentences” (e.g., follow “Kitty eat” with “Yes, the kitty is eating”).

Early Childhood (2–6)

What You Might Observe:

• Rapid advances in vocabulary and syntax
• Incomplete understandings of many simple words (e.g., undergeneralization, overgeneralization, confusion between simple comparatives such as more vs. less)
• Overregularization (e.g., foots, gooder, goed)
• Overdependence on word order and context (instead of syntax) when interpreting messages
• Superficial understanding of what “good listening” is
• Difficulty pronouncing some phonemes and blends (e.g., r, th, sl, dr)
• Increasing ability to construct narratives

Early Adolescence (10–14)

What You Might Observe:

• Increasing awareness of the terminology used in various academic disciplines
• Ability to understand complex, multiclause sentences
• Emerging ability to look beyond literal interpretations; comprehension of simple proverbs
• Emerging ability to carry on lengthy conversations about abstract topics
• Significant growth in metalinguistic awareness

Diversity:

• Frequent readers tend to have larger vocabularies.
• Girls are more likely than boys to converse about intimate and confidential matters.
• African American teens may bandy insults back and forth in a playful manner.
• Adolescents may prefer to use their native dialects even if they have mastered Standard English (see discussion in “Ethnic Differences” section).

Implications:

• Begin to use the terminology used by experts in various academic disciplines (e.g., simile in language arts, theory in science).
• Use classroom debates to explore controversial issues.
• Present proverbs and ask children to consider possible underlying meanings.
• Explore the nature of words and language as entities in and of themselves.

Late Adolescence (14–18)

What You Might Observe:

• Acquisition of many terms related to specific academic disciplines
• Subtle refinements in grammar, mostly as a result of formal instruction
• Mastery of a wide variety of connectives (e.g., although, however, nevertheless)
• General ability to understand figurative language (e.g., metaphors, proverbs, hyperbole)

Diversity:

• Boys are apt to communicate their thoughts in a direct and straightforward manner; girls are more likely to be indirect and tactful.
• A preference for one’s native dialect over Standard English continues into the high school years.

Implications:

• Consistently use the terminology associated with various academic disciplines.
• Distinguish between similar abstract words (e.g., weather vs. climate, velocity vs. acceleration).
• Explore complex syntactic structures (e.g., multiple embedded clauses).
• Consider the underlying meanings and messages in poetry and fiction
• When teenagers have a native dialect other than Standard English, encourage them to use it in informal conversations and creative writing; encourage Standard English for more formal situations.
